MACHINE FOR COATING.

Specification of Letters Patent.

Patented April 13, 1909.

To all whom it may concern:

Be it known that I, FREDERICK'E. GOLD- SMITH, a citizen of the United States, and a resident of Middletown, in the county of Butler and State of Ohio, have invented a new and useful Machine for Coating, of which the followi a specification. v

This invention relates to a machine for coating objects such, for instance, as tile.

An especial object of the invention is to provide a very compact and self-contained ap ratus for appl coating.

he characteristlcs 'andadvantages of the invention will hereafter be more particularly pointed out in connection with the accomnying drawing which illustrates exempli- 'ng structures in which the invention is embodied.

.Inthe drawing: Figure 1 is a longitudinal section; Fig. 2, a crosssection at a, 1

and 3, an endview at b, Fig. 1.

1, I are standards resting on any suitable 'sup ort; 2, a head mounted so that it may v.omi late in the left-hand standard; 3, a

hollow extension of the head; 4, one or more jacent to the righthand standard; 6, a shaft revolubly' mounted in the right-hand standard through which it extends andis there splined to a bore in the head 5 of shaft 6 and is driven from any suitable source of power and serves to rotate the head; 7, a tubular shell, usually metallic, revoluble at the left hand end on anti-friction roller or rollers 4 and secured at the ri ht hand end to revoluble head 5 by whic it is rotated; 8, perforations in shell 7; 9, counter-bores in per.- forations 8 flaring toward the surface of the shell; 10, a general designation of the frame carried within the shell 7; 11, the left end of the frame 10; 12, a bolt passi head 2 and'having a screw-three engaging through a thread in abore of frame portion 11; 13, right-hand end of frame 10 having a bore fit tirig over: the hub formed in the head 5; 14, a

which I term a suction roll; 15, its shaft; 16, flanges on shaft 15; 17, thimbles of antifriction metal-forming bearings for end of shaft 15'; 18, housings-for bearings 17 in frame 10; 19, tops of the housings 18; 20, springs in sockets in frame 10 pressing against t e lower sides of bearings 17 serving to urge roll 14 with a 'elding pressure toward the inner surface 0 shell 7; 21, a tube suitably supported in the ends of frame 10 and passing through left-hand standard 1; 22, a spout communicating-with tube 21 and termlnating in discharge opening 23 adjacent to the inner surface of the shell; 24, a longitudinal member on the spout in contact with the innor surface of the shell; 25, a rotatable collar having a handle 25 and centered with relation to the head 2 by an annular socket 26 provided therein; 27, bayonet joint members on collar 25 cooperating with studs or clips 28 on standard 1; 29, a pointer on head 2; and 3.0, index marks on standard 1.

The position of suction roll 14 and spout 22 in relation to the vertical may be adjusted by rotating head 2. The pointer and scale 30 afford a guide for this adjustment. The head 2 is secured in the machine at adjusted position by throwing the handle 25 of collar 25, so that bayonet clutch members 27 engage studs 28. By unlocking the collar 25. the head 2-, frame 10 and related parts, and shell 7 may be readily removed through the hole in standard 1.

In operation coating material from any suitable source is introduced by any suitable means into tube21 and thence to s out 22 from which it issues at 23. The shel 7 is...

in the meantime rotated in thedirection of the arrow by shaft 6, and suction roll 14 in contact with the shell is also rotated in the same direction. The coating material issu;

ing from opening 23 is prevented from pass ingdown to the ri ht between the spout and shell b the longitudinal rib 24. The unaterial, owever, passes to the surface of suction roll 14 and as the shell and roll rotate is forced out through erforations in the shell '7 to the surface of t e shell where it forms a kind of fountain or mound extendlng along the upper exterior surface of the shell. This mound or head of color is carried approxi-- mately centrally over the contact polnt of a result in many cases a superfluous amount iio The adtion of from the tile s it leaves. the shell and any carried on the shell.

of coating'mate 'al might be deposited, es-

ecially on the e ges of the tile and particuarly thelast e ge passing over the shell. e suction roll, however, in the present inv ntion, is such that the coating material is I apidly drawn down and away aterial is removed reventing the forr'natio of beads or 0t er imperfections on t e tile. As the coating material is carried 0 beyond the contact point of the shell and roll and is drawn inward by the suct )11 roll it falls through the shell and into a suitable receptacle placed to catch the overflow. Coating material is prevented from getting upon the bearings or other running arts of the. machine by various meanslanges 16 on shaft 15 serve for thispurpose. I

Any desired device maybe used for feeding biscuit or other objects to be coated over the shell 7. Usually a pressure roll is mounted in the standards abov the shell serving .to the shell as they pass over it and receive a deposit of coating material on their under sides from the fountain or mound of material The construction of the shell and suction roll may bewidely varied. It is, however,

desirable that the suction roll shall have a surface layer of flexible or elastic material such-as rubber, and it is also desirable that the shell shall be of such material or pro ortions as to be to an extent yielding, flexi 1e, or elastic.

* While, the structures as shown represent a convenient and desirable embodiment of my invention, I consider the said invention broadly new with me, and do not intend to limit myself in any respect to details of construction.

'WhatI claim is:

1." In a machine for-coating, a rotary pervious shell, and an elongated continuous spout for discharging coating material within t e shell so that it passes to the. outer surface thereof.

. 2. In a machine for coating, the combina-' tion of a rotary pervious shell, a roll within the shell, and means for discharging coating rnateiial within the shell adjacent to the roll so that it shell. I

3.

8.' In'coating apparatus, the combination of a rotary pervious shell and a roller within the shell engaging its inner surface.
